Chara scores twice as Bruins blank Flames

BOSTON (AP) - Zdeno Chara scored two power-play goals and Jarome Iginla had a pair of assists against his former team to help the Boston Bruins beat the Calgary Flames 2-0 on Tuesday night.

David Krejci also had two assists and Tuukka Rask made 21 saves for the Bruins in their third straight shutout of the Flames in Boston. Rask picked up his third shutout of the season and extended Calgary's scoreless streak in Boston to 189 minutes, 36 seconds.

Reto Berra kept Calgary close, stopping 29 shots as the Bruins controlled play most of the game.

Boston outshot the Flames 31-21 one week after rallying for a 2-1 win in Iginla's return to Calgary, where he played 16 seasons and spent nine as the team's captain.
